STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 599,459, dated February 22, 1898. Application filed April 26, 1887. Serial No. 236,252. (No model.)

To all whom it may concern.-

Be it known that I, FRED TERSTEGEN, of Elizabeth, in the county of Union and State of New Jersey, have invented a new and useful Stem finding and Setting WVatch, of which the following is a specification.

My invention relates to the setting-wheel of a stem winding and setting watch and to adjusting a setting-wheel in and out of connection with a dial-wheel connected with one of the hands of the watch, whether such connection be made by an intermediate wheel between the setting-wheel and the dial-wheel or by adjusting the setting-wheel to gear directly with a dial-wheel which carries the hand.

My invention further relates to a locking and holding device by which a setting-wheel is held in connection with a dial-wheel.

My invention further relates to the looking or holding devices by which a stem-driven train and a setting-wheel are held in connection with a dial-wheel for the purpose of setting the hands of a watch by the stem.

My invention further relates to means of breaking the connection between a settingwheel and a dial-wheel or disengaging the dial-wheel and hand from the setting-wheel.

My invention further relates to means of releasing a stem-driven train from its setting position and returning it to its winding position.

The objects of my invention are, first, to construct a stem winding and setting watch which shallbe practically dust-tight; second, to make the various operations of a stem-setting mechanism whereby a setting-wheel is adjusted for connection and locked into engagement with a dial-wheel,whether such connection be direct or through an intermediate wheel,and whereby a setting-wheel is released and disconnected from and held out of engagement with a dial-wheel also, to make the various operations whereby a stem-driven train is locked or held in its setting position, and whereby a stem-driven train is released from its setting position and returned to its winding position; third, to automatically break the connection between a stem-driven train of stem-setting watches and a dial-wheel in gear with a minute-hand and establish a connection between the same stem -driven train and a-dial-wheel in engagement with a wheel 011 the seconds-hand of a watch for the purpose of setting the seconds-hand independently of the minute and hour hands by the same stem-driven train, for to arrange these changes in the position of the stem winding and setting mechanism I apply a weight or weighted part that is caused to gravitate, whereby it becomes an operative element in the said mechanism, as will be hereinafter described.

In the accompanying drawings, Figure 1 is a plan view of a portion of a watch, showing the position of the winding and setting mechanism. The setting-wheel is held out of gear with the dial-wheel, and the stem-driven train is in the winding position when the watchmovement is held with its stem up, which is generally the position of a watch when carried in the pocket. Fig. l is a plan View of a stem-driven train without the yoke and a finger F, which by its weighted part can be caused to swing toward the crown-wheel K when the stem is held downward and is engaged by the crown-wheel when the stem is rotated backward. Fig. 1 shows also a plan View of the yoke Y, which is placed over the crown-wheel K and the finger or weighted part F, which has apin f bearing against the adjacent edge of the projection ,2" of the yoke, and also shows a detail of a plan of the finger orweightedpart. Fig. l representsthelever L, showing the end of the short arm l beveled so as to be tangential to the segment of the circle (shown in dotted lines) in which it moves and also showing the dong arm Z of the lever L without the piece (represented by dotted lines) commonly provided on a lever which extends out of the movement through a hole provided for it into the movement and by which commonly the yoke is set by being drawn out of the movement. My improved leveris without such piece. Fig. 1 is an edge elevation of the yoke Y, the wheel I, and crown-wheel K, and also shows the finger or weighted part F, with pin f, bearing against the projection 2 of the yoke. Fig. 2

is a plan view of a portion of a watch, parts of my invention being detached therefrom, and shows the lever L attached to the watch. Fig. 2 represents a bottom, top, and edge view of the setting-lever P, the recesses for the wheels being shown in the bottom View, and also a bottom and edge view of the setting-wheel S. Fig. 2 is a plan view of the setting-wheel S, pivoted to the lever P, and the position thereof when it is held out of gear with the dial-wheel d when in its normal position, as shown in Fig. 1. Fig. 2 also shows a plan view of a weight W, which can be caused to gravitate, whereby it will lock the setting-wheel in or out of engagement with the dial-wheel d. Fig. 2 is a plan view of the weight 7 and the arm 19 of lever P in contact therewith and resting on the step w, which is the locking device for the settingwheel. Fig. 2 is a plan view of the lever, P and part of the weight WV, showing the setting-wheel S in gear with the crown-wheel K, by which the setting-wheel is turned. Sheet 11, Fig.3, is a plan View of aportion of a watch, showing the position of the finger or weighted part F when the watch is held with its stem up. Fig. 4 is a like view of the same, but the position of the finger or weighted part F is changed when the watch is held with its edge up and with its stem in a horizontal line. It also shows the weight in dotted lines and the position of the lever L toward the weight NV. Fig. 5 is a like view, but the watch is held with its stem down, and shows the position of the finger or weighted part, which is now in engagement with the crown-wh eel K, and the pin f on the finger or weighted part bears now against the edge of the projection e" of the yoke Y. Fig. 6 is a like view showing the watch held with its stem down, which is rotated a little rearward or to the left, showing the position of the finger or weighted part F, which is engaged now and turned by the crown-wheel K, and the pin f of the finger, bearing against the projection .e" of the yoke, turns the yoke Y when the said finger or weighted part F is turned by the crown-wheel K and stem. In this figure are also shown antifriction-rollers R, attached to the plate A, whereby the weight can be held and prevented from rising off the pillar-plate. Fig. 6 is a perspective View of a weight having an antifriction-roller pivoted to it. Fig. 6 is a perspective view of a weight havingits inner and outer edge beveled off and showing the construction of antifriction-rollers applicable to the pillar-plate, as shown in Fig. 6. Fig. 7 is a plan View of a portion of a watch with a weight WV placed thereon, the watch being held with the stem downward, whereby the weight is caused to gravitate toward and against the lever-arm Z of the lever in position to gravitate further and lock the stemdriven train from the winding position when by the backward rotation of the stem E the yoke is moved to permit the lever-arm Z to pass under the projection 2 Fig. 8 represents the same when the backward rotation of the stem has been made, showing that by the further gravitation of the weight the lever is turned, whereby-its arm Z is carried under the projection .2 and the arm Z into the its setting position.

notch 10, thereby holding and locking the stem-driven train. Fig. 9 is a like view showing the lever P, with the setting-wheel S,which is held or locked in gear with the dial-wheel when the weight locks the stem-driven train out of its winding position. v Fig. 9 is a plan view of setting-lever P, with the setting-wheel S in gear with the crown-wheel and out of gear with the dial-wheel d. Fig. 9 is an edge elevation of the setting-wheel S in gear with the dial-wheel d. Fig. 10 is a plan view of a watch held with the edge up and the stem between a pendent vertical position and horizontal position, in which position the hands can be most conveniently set and where the setting-wheel S remains in gear with the dialwheel. Fig. 10 is an edge view of the pillarplate, the rim being broken away to expose the weight 1V and lever L and finger or weighted part F. Fig. 11 is a plan view of a part of the same watch after the hands have been set and the weight caused to gravitate by raising the stem above a horizontal line for the purpose of automatically disengaging the setting-wh eel S from the dial-wheel and automatically releasing the locking device of the stem-driven train and automatically returning the stem-driven train to its winding position. Fig. 11 is an edge elevation of the setting-wheel S out of gear or disengaged from the dial-wheel (1, Sheet IV. The drawings on this sheet represent the principle of operating the setting mechanism by causing a weight to gravitate, extended to set a seconds-hand independently of the hour and minute hands. Fig. 12 represents the watch held stem downward and the weight in the position it assumes after gravitating, the setting-Wheel being in gear with the dial-wheel and the stem-setting train locked in its setting position by the lever L, the short arm of which is under the projection 2 of the yoke and the long arm held in a slot N of the weight. The setting-lever 5, which carries the seconds-setting wheel, is held by its arms 5 and 5*, bearing against the edge of the weight in. position to retain the wheel 2 on its arm 5 out of engagement with the seconds-hand wheel 1. Fig. 13 represents the watch held with the stem in a horizontal position, by which the weight is caused to gravitate away from the stem far enough to permit the arm 19 of lever P to drop off the step it), and thus put the setting-wheel S out of connection with the dial-wheel, but not far enough to release the lever L, the short arm Z of which remains under the projection 2 of the yoke, and thus retains the yoke locked in The arm 5 of the lever 5 by this movement of the weight drops into the notch O of the weight and the arm 5 rises on the lug g, whereby the lever-arm 5 is turned, and the wheel 2 is connected with the seconds-hand wheel 1. The seconds-hand can now be set by the stem without moving the hour and minute hands. Fig. 14 represents the watch with the stem held upward, in which position the weight is caused to gravitate away from the stem, whereby the wheel 2 is caused to disconnect from the secondshand wheel 1 by the arm 5 passing out of the notch O and the arm 5 passing off the lug 9, thereby turning the lever and the lever-arm Z to pass from under the projection .2 of the yoke, whereby the stem-driven train is re leased and returns to its winding position. Fig. 15 represents a watch held with its'stem downward to cause the weight to gravitate and at the moment when the weight has gravitated far enough to strike the pawl F and move it into position to engage the crown-wheel K, the stem-driven train being still in its winding position, with the wheel I in gear with the winding-wheel B. Fig. 16 represents the same after the stem has been rotated backward, the stem-driven train being in this case out of its winding position; but the setting-wheel S is not in connection with the dial-wheel, the yoke not having been turned far enough to cause the pawl F to be released and allow the weight to gravitate to its full extent and to the position it occupies in Fig. 12. Fig. 17 is a view of the secondssetting-wheel lever 5. Fig. 18 represents a cross-section, enlarged, of the secondsset wheel 1, which moves the seconds-hand and forms a dial-wheel for the seconds-hand, this wheel being placed and held by friction on the staff of the seconds-hand pinion usually employed in watch mechanism.

Referring to the annexed drawings, A represents the pillar-plate of a watch-movement, which is fitted to and secured in the case C in the usual manner. \Vithin the pendant c is journaled a stem-arbor E, the inner end of which enters into and engages the tubular stem of a winding-pinion e, that is journaled in a suitable bearing under the plate A, and has aportion of its toothed periphery projecting through an opening a, provided for it in said plate and is thus caused to mesh with or engage the teeth of the crown-wheel K, journaled in the plate. This arrangement is of such a nature as to permit the crown-wheel to be rotated in either direction by means of the stem-arbor. The yoke Y is pivoted to a hub on the pillar-plate and held in place by a cap and screws, as usual. At one end of the yoke is pivoted an intermediate windingwheel I, which, when the yoke is in its winding position, transmits the motion of the crown-wheel to the barrel arbor-wheel B.

D is the minute-wheel, and d the cannonpinion, these wheels being called the dialwheels.

S is theintermediate setting-wheel for transmitting the motion of the crown-wheel to the dial-wheels when the yoke is in its setting position.

The above-described mechanism of a stem setting and winding watch is of well-known construction and does not differ in operation from similar mechanisms found in other watches, except as modified in the manner hereinafter described by the mechanism and modes of operation peculiar to my invention.

I will now describe in detail my novel devices for moving a stem-driven train out of engagement with the barrel arbor-wheel B or out of its winding position to its setting position and into engagement with the dial- Wheels,and also the means by which the stemdriven train is caused to disengage itself from the dial-wheels and reengage the barrel arbor-wheel.

Sheets I to III, Fig. 1, represents the watch with the stem upward. This is the position it usually occupies in the pocket. In this position the stem-driven train is always in gear with the winding mechanism. The mech anism by which the stem-driven train is put in gear with the dial-wheels consists of a finger or weighted part F, lever L, and a pivoted setting-lever P, carrying the settingwheel S. The yoke Y has a projection 5, under which the finger or weighted part F is pivoted to the watch-plate. This finger has a gravitating extension which causes it to swing or turn on its pivot when the watch is turned from a position where the stem is held upward, Fig. 1, to a position where the stem is held downward, Fig. 8, the positions the finger or weighted part assumes automatically as the stem of the watch is changed from an upward to a downward position being clearly shown by full and dotted lines in Figs. 3 to 5, Sheet II. hen in its downward position, Fig. 5, the finger or weighted part engages the crown-wheel, as indicated by the dotted lines in Fig. 1, Sheet I. hen this engagement takes place, turning the watch-stem to set the hands causes the finger to turn until its pin f bears against the adjacent edge of the projection 2' of the yoke, as shown in Figs. 1 and 1, and further turning of the crownwheel causes the finger or weighted part to move farther, and the pin f bears against the said projection and turns the yoke to its setting position, whereby the wheel I is disengaged from the barrel arbor-wheel B, or, in other words, the stem-driven train is disengaged from the winding mechanism. L is a lever pivoted to the plate and having a short arm Z, the end of which is beveled off so as to be tangential to the segment of the circle in which it moves, as shown in Fig. 1 and the said end is set behind the projection Z2 of the yoke and serves as a stop when the yoke is in its setting position-that is, when the stem-driven train is locked out of its winding position. The longer arm Z is nearly at right angles to the shorter arm and its free end is in juxtaposition to the forward end of the sliding weight IV, hereinafter described.

The sliding weight IV in the present instance has the shape of a segment of a circle and its segmental peripheries or inner and outer edges are concentric to the center of the watch. It is held between the pillar-plate rim and two or more guide-pins inserted in the pillar-plate, so as to slide easily in a circular path to a limited eXtent, but without perceptible lateral motion. The weight W may bear directly against the rim of the pillar-plate and the guiding-pins, or it may be provided with an antifriction-roller R, let into the outside edge to reduce friction between its edge and the rim, or similar anti- 'friction-rollers may be placed on studs inserted in the pillar-plate on each side of the weight, so that its two edges will be in contact with said rollers. The antifriction-rollers may also have conical flanges between which the edges of the weight will be held, and thus prevented from rising off the pillarplate. (See Figs. 6, 6, and 6 The weight WV performs the following functions, viz: It looks the setting-wheel in gear with a dialwheel; it looks the stem-driven train out of its winding position; it automatically disconnects the setting-wheel from the dial-wheel and, as illustrated on Sheet IV of the drawings, puts the stem-driven train in connection with the seconds-setting wheel, while retaining the stem-driven train in its setting position, and, finally, it automatically releases the stem-driven train for the purpose of disconnecting it from the setting mechanism and permitting the stem-driven train to return to its winding position. For the performance of these functions the weight is caused to gravitate.

The setting-lever P is shown in detail in Figs. 2 and 2. It has two arms 1) p, the former being in proximity to the forward end I) of the weight and the latter near the rear end I). In its under side are two recesses or wheel-seats, in one of which the settingwheel S is placed and pivoted. The said lever is pivoted to the pillar-plate at 19 and in this position the setting-wheel S is always in gear with the crown-wheel K, (see Figs. 1 and 2 whether the setting-wheel is in or out of gear with the dial-wheels; also one or the other of the arms 19 p is at all times in contact with the inner edge of the weight. In Fig. 2 where the setting mechanism is out of gear and the weight in its farthest backward position, the arm 19 rests against the inner edge of the weight and the settingwheel S is thereby held out of gear with the dial-wheel, while in Figs. 2 and 2 where the setting mechanism is in gear, the said arm is not in contact with the weight, while arm 9 is in contact therewith and rests on the step w, which is the locking device for the setting-wheel. WVhen, for example, the weight slides or gravitates toward the stem, the step to on the forward end of the weight passes under the arm 1) and the arm 19 passes from the rear end of the weight and the said setting-wheel S is held or locked into connection with the dial-wheel. When' the weight moves or gravitates in the opposite direction, the rear end 5 thereof strikes the end of arm 10 at the instant the arm 19 passes off the step, and by this movement the lever is turned on its pivot 19 the arm 19 passing up on the edge of the weight and the arm 1) dropping off the step 10, and thereby the setting-wheel is antomatically disengaged and held out of gear with the dial-wheel.

Iwill now describe the manner in which the setting-wheel S is brought in gear with the dial-wheel. Sheet II, Fig. 3, showsthe finger or weighted part F disengaged from the crown-wheel K, as the watch-movement is held with the stem up. By turning the watch to the right, as shown in Fig. 4, the finger or weighted part changes its position, gravity acting on its weighted tail and making it follow the movement of the watch, and when the watch is held with the stem downward the finger or weighted part is in engagement with the crown-wheel and its pin f is in contact with the edge of the projection z of the yoke. The lever L remains in its normal position. In Fig. 5 the watch is represented with the stem held down, and the yoke is held in its winding position by the spring y. Now when the stem E is rotated in a reverse direction from which it is turned to wind the watch the teeth of the wheel I are caused to slip over the teeth of the winding-wheel with a clicking sound and a vibratory motion is given to the yoke, and when the crown-wheel engages the finger or weighted part and turns it, the pin on the finger or weighted part being pressed against the edge of projection a on the yoke turns the yoke to the position shown in Figs. 6 and 7, whereupon the intermediate wheel I is disengaged from the winding-wheel, and the stem-driven train is put in gear with the dial-wheel by the motion of the lever P, caused by the rotation of the stem and crown-wheel, thus carrying the settingwheel S in gear with the dial-Wheel, and the weight WV, gravitating the lever L, is adjusted to hold the yoke steady, whereby the locking of a stem-driven train out of its winding position is effected. These results are produced in the following manner, referring to Figs. 8 and 9, Sheet III: When the weight gravitates toward the stem, its curved front end I) comes in contact with the end of the long arm Z of the lever, as shown in Figs. 4 and '7, and causes the arm to turn toward the rim of the plate and enter a notch 20 in the outer edge of the weight, as shown in Figs. 8 to 10, and when in this notch the arm is held and the lever prevented from moving. when, as before stated, the yoke Y was moved by turning the stem in the direction to set the watch, the projection .2 was moved far enough to allow the beveled end of the lever-arm Z to ride upon the face of the projection e Hence the turning of the lever by the weight W carries the end of arm l against said projection and to a position where it looks the yoke in its setting position, the stem-driven train being now in connection with the dial-wheels. By reference to Fig. 10, Sheet III, the position of the several parts of the setting mechanism will be plainly seen. The hands can tion, as shown in Fig.10.

To disengage the stem-driven train from the setting mechanism, the watch is turned to its right position, with the stem above a horizontal line, as in Fig. 11. The effect of this is to cause the weight W to gravitate away from the stem and thereby release the lever L automatically, and the yoke being pressed back by its spring y forces the arm Z from against the end of the projection .2

and the yoke is swung to its winding position with the wheel I into engagement with the wheel B. By the same motion of the weight the rear end thereof strikes the arm 1) of the lever P, thus throwing the arm 19 off the step, and thereby the setting-wheel is automatically disengaged from the dial-wheel.

It must be understood that the stem-driven train cannot be put in connection with the dialwheel so long as the arm Z of the lever is held behind the projection 2' because the weight is prevented by the end Z of the lever from moving far enough for its rear end I) to pass out of the path of movement of the arm 29 of the lever P, and thus the accidental or unintentional connection of the stem-driven train with the dial-wheels is avoided. Hence it is always necessary first to turn or place or hold the watch in a prearranged or previously-determined position or with its stem directly downward, or nearly so, to cause the weight or weighted part to gravitate, then to rotate the stem backward for the purpose of turning the yoke far enough to allow the weight by gravitating to turn the arm Z of the lever against the proj ection .2 and lock the yoke, the arm Z entering the notch of the weight and the weight gravitatin g far enough for its step 2.0 to reach the arm 19 of the lever P and lock the same.

I will now describe in detail my novel devices for moving the stem-driven train out of engagement with the barrel arbor-wheel B and locking the stem-driven train, and my novel devices for automatically disengaging the setting-wheel S from the dial-wheel,which moves the minute-hand, and to automatically engage the stem-driven train with the secondsset wheel 1, which moves a seconds-hand.

Sheet IV, Fig. 12: The stem-driven train is the same as in Fig. 1, Sheet 1, and the watch is shown as held with the stem downward. The lever L,with its arm Z, is set against the end of the projection 2 of the yoke by the gravitation of the sliding weight W, and the pivoted lever P is turned by its arm 19 passing up on the step 10 of the weight, and the setting-wheel S is locked into engagement with the dial-wheels. Then the watch is held with its stem down, as in Fig. 12, the weight gravitates, and the end Z of the lever L entering a slot N in the weight is turned by the weight and its arm Z is set against the end of the projection .2 of the yoke, when the stem-driven train is locked in its setting position, as heretofore described. When the watch is held with its stem upward, as shown in Fig. 14:, the weight gravitates and moves the arm Z of the lever from against the end of the projection a of the yoke, whereby the yoke is released and swung back by the pressure of spring y to its normal or winding position and at the same time the lever is disconnected from the weight. To turn the yoke Y of a stem-driven train out of the winding position into the setting position-that is, its wheel I out of gear with the barrel arbor-wheel B-the watch is held first with its stem down, as shown in Fig. 15, the sliding weight gravitates, and its shoulder 'v strikes the finger or pawl F and moves the same into gear with the crownwheel. hen the stem is rotated to set the hands, the crown-wheel revolves and moves the finger or pawl F, which turns the yoke Y, and the wheel I is disengaged from the barrel arbor-wheel B, as shown in Fig. 16. By rotating the stem farther the pawl F is moved by the crown-wheel from behind the shoulder 41 of the sliding weight IV, and the weight continuing to gravitate its shoulder comes in contact with the arm Z of the lever L and moves the latter into the slot N of the weight, whereby the lever-arm Z is set against the end of the projection of the yoke, which is thereby locked and held, and the stem-driven train is locked out of its winding position, the pawl F, by coming in contact with stud it on the pillar-plate, is turned thereby and thrown out of gear with the crown-wheel, and the arm 19 of the lever P comes in contact with the step w of the weight, and being raised thereby the setting-wheel S is brought into engagement with the dial-wheel d, as shown in Fig. 12. The finger or pawl F is pivoted to the under side of projection z of the yoke Y and can be turned to the crown-wheel, so as to engage one tooth thereof and thereby connect the yoke and crown-wheel together, so that when the latter is turned by the stem in the direction to set the hands the yoke is turned and the wheel I thereby put out of gear with the winding-wheel B, and the projection .2 is placed in position to be engaged by a locking device or lever-arm Z of the lever L, when the latter is thrown into position by the gravitating weight IV. The pawl F is normally held out or away from the crownwheel by a hair-spring H, which is indicated by dotted lines, fixed to the under side of the yoke and bearing against the pawl F in such a manner as to keep it away from the crownwheel K, as shown in Figs. 12, 18, and let. When the watch is held with its stem down, as in Fig. 15, the projection or shouldero of the weight strikes the pawl F, lying in the path in which the weight gravitates, and thereby engages the said pawl and moves it into engagement with the crown-wheel. By the movement of the crown-wheel the said pawl is carried away from the shoulder 11 of the weight, (see Fig. 16,) and the weight now slides or gravitates farther and carries in its slot N the lever-arm L and turns the lever and arm Z from behind and against the face of the projection e of the yoke, thereby looking the stem-driven train out of its Winding position, as shown in Fig. 12. The releasing of the pawl follows the locking of the yoke by the same motion of the crown-wheel 'and stem. The pawl F is disengaged from the crown-wheel by coming in contact with a screw or stud u, inserted in the pillar-plate in the angle formed by the projection 2 and in such a position relatively to the crown-wheel and pawl that when the yoke reaches its setting position the pawl will be disengaged from the crown-wheel. The stem-driven train is now in position to engage the dial-wheels d, as before described. Now to set the watch correctly, suppose the hands to show eleven hours and fifty-seven minutes, as shown by dotted lines in Fig. 12, while the correct time is one minute and a half after twelve. The minute-hand is set up to one minute and a half after twelve, as shown by the solid lines. Before moving the hands the minute-hand and seconds-hand corresponded, but after turning the min ute-hand to a half-minute the seconds-hand is thirty seconds behind and must be set to the half-minute or thirty-seconds position. This is done by an independent seconds-setting mechanism, which I will now describe.

Referring to Fig. 15, in one of the recesses of lever P (shown in Fig. Sheet 1) on the pivot 19 is placed a wheel 3, which is always in gear with the setting-wheel S, and the said setting-wheel S is always in gear with the crown-wheel, as before described, and the wheel 3 is turned thereby. 5 is a pivoted lever, to the under side of arm 5 of which is pivoted a wheel 2, which is held always in gear with wheel 3 by the lever-arms 5 and 5 resting against the inner periphery of the sliding weight lV, as shown in Figs. 15, 12, and 14. On the sliding weight is formed a projection or lug g and a notch 0 of such length apart as to correspond with the ends of the lever-arms 5 and 5 of the pivoted lever 5. As before described, when these lever-arms 5 and 5 rest against the inner periphery or edge of the sliding weight W, as shown in Figs. 12, 15, and 16,.the wheel 2 on the arm 5 is always held in gear with wheel 3 on the pivoted lever P, but out of gear with the wheel 1, which is a dial-wheel for the seconds-hand and is placed on the staff or pivot 1 of the seconds-hand wheel of the watch mechanism, as shown in Figs. 12, 13, and 14, and in detail and cross-section, Fig. 18.

When the watch is held with the stem down, as shown in Fig. 12, the weight gravitates and sets the setting-wheel S in gear with the dial-wheel by the step to raising the arm 13 of the lever, as before described. Now by turning the watch while still held with the edge up until the stem is in the horizontal position and on the right-hand side, as shown in Fig. 13, the weight gravitates away from the stem far enough for the step to pass from under the arm 19 and the end of the weight to strike the arm 19, and thereby turns the lever P and. the setting-wheel S automatically out of gear with the dial-wheel cZ. At the same time the lug g comes in contact with and lifts the arm 5 of the setting-lever 5 and the arm 5 passes into the notch 0. By this movement the lever 5 is turned and the wheel 2 is moved automatically into gear with the seconds-set wheel 1. hen the lever 5 is thus adjusted by the movement of the weight, the lever L remains in the slot N of the weight and its arm Z against the projection 2 of the yoke. The object of this is to hold the yoke and keep and lock the stemdriven train in gear with the seconds-set wheel 1. Now the seconds-hand can be set in either direction and to any point on the secondsdial by means of the stem and without moving the minute-hand, and therefore it can be set from the full minute, as indicated by the dotted line, Fig. 13, to the half-minute or thirty-seconds position and made to correspond to the minute-hand, as shown in Figs. 13 and let in solid lines. As soon as the seconds-hand is set to the rightpoint the stem of the Watch is turned toward the upward position, whereupon the weight gravitates and the lug passes from under the arm 5 and arm 5 passes out of the notch onto the edge of the weight, and thereby turns the lever 5 and the wheel 2 automatically out of gear with the seconds-set wheel 1. At the same time the weight moves the locking device automatically or the lever-arm Z away from the projection 2 of the yoke, and the yoke-spring y swings the yoke and the stem-driven train into its winding position, and when the projection passes from the arm Z the sudden swinging back of the yoke gives an impulse to the lever, which strikes the shoulder of the weight and thereby turns it back, as shown in Fig. 14.

From the foregoing description itwill be seen that the locking of the stem-driven train out of its winding position takes place by causing a weight to gravitate, whereby the looking device moves to retain a stem-driven train for setting the hands when the yoke is brought to the setting position, and the releasing of the stem-driven train from its setting position also takes place by causing a weight to gravitate, the locking device being released automatically and the stem-driven train returning to its winding position.
